Bataille unloader cam mechanism relates to the field of textile machinery to surf to the edge of the weft fabric on the loom. The technical result is achieved in that Bataille mechanism of a loom, it comprises a batten, the main shaft of the loom to the cam and counter-cam, podbatanny shaft of the loom and has at podbatannom shaft loom cam discharger consisting of a cam on which the roller moves pivotally mounted on the rocker a yoke connected to one end of the spring and the other end pivotally attached to the frame of the weaving machine. With this structure, the cam spring unloader is batten drive energy. Cam cam unloader performs the function of controlling the distribution of the energy storage spring and the transfer of energy from the spring required to fully balance the forces of inertia of the batten and creating backlash reciprocating rocking motion of the batten. This will also reduce the number of transitions of the batten roller and the cam on the counter-cam, reduce the number of impacts to the mechanism of the weaving machine and reduce the unevenness of rotation of the main shaft of the loom, to reduce the reaction in the kinematic pairs, reduce noise and vibration, improve durability and reliability of the loom.
